To all whom it may concern.'

Be it known that I. HARRY E. BALLARD, a citizen of the United States,and' resident of Holyoke, county of Hampden, Commonwealth ofMassachusetts, have invented an lniprovementin Binders for FoldingDoors,of which the following description, in con,- nection with theaccompanying drawings, is a specification, like characters on the'drawlings representing like parts ineach of the several views.

This invention relates to folding doors and more particularly to abinder and operating device therefor adapted to hold the same closedsecurely but heilig instantly and easily y ieleasable, with an actuatingdevice that may also constitute the instrumentality for moving the doorto open position. The foregoing and other objects and advantages of theinvention will more fully appear ironi the following detaileddescription, and the distinctive featuresofnovelty will be pointved outin the appended claims. Referring to the drawings:

Fig. 1` is a plan view showing my 1mproved binder applied to yafo'ldingdoor.

F ig. 2 is a plan view on a relatively enlarged scale of the binderdevice with the portionsof the .door adjacent the central hinge. v nFig. 3 is a partial front elevation with-intermediate portions brokenlaway showing the binder device applied to a door. n

Fig. l is a plan view of a slightly modilied form of thevbinder deviceapplied` to a door, portions of the door being shown in horizontalsection, and with the door in partially open position.

Fig. 5 is a view similar: to Fig. 1 but showing the position of theparts with the door closed; and y Fig. 6 is a partial front view of thebinder device of Figs. l and 5 applied to the door. 10, 11 indicate twoportions of a folding door hinged together by hinges The door portion 10has its outer side hinged at 13 to a relatively stationary wallorsupport 14,'while the portion 11 may have itslouter side engaged. witha hanger 15 suitably guided in an overhead support (not shown). Thesetwo door portions when in door closingposition, close the openingbetween the wall 1a and a wall 16.1,; One of the door portions, shown asthe portion 11 is equipped vat top and bottoni with stout bars 1?.,18

`fixed thereto by screws or otherwise atfthe side of the door oppositethe hinges 12and projecting some distance horizontally over the otherdoor portion 10 as indicated at 17, 18a. The door portion 10hasfixedlthereto adjacent its inner edge,aplurality` of brackets 19 invertical alignment,` there being three or" these brackets shown,adjacent the top and bottom of the door, and at an intermediate pointrespectively. All of these brackets may be' alike, comprising as shown aplate 19?' .secured to the door by screws 20, and having formedtherewith a bearing collar orring 19b projecting outward therefrom.

The lower one of the brackets 19 is shown as applied to the door ininverted position in respect to the others for ay purpose that willappear. The upper andlower bearing collarsA 191 have fitted to turntherein, hollow tubes 21 borne by cain heads 22, the one of these camheads associated with the upper collar 19D extending upward therefromand the one -associated with the lower collar eX- ,n

tending downward therefrom as shown,

these heads having bearing engagement with the collars 19h. Thesehubsand cam heads are formed withsquared sockets in which are litted theends of a squared shaft or bar the cam heads being secured to this shaftby suitable means shown `as clamp screws 211;. f The cam heads 22 areformed with cam faces 22Z1 which, as the shaft 23is turned ,in onedirection, i. e. to the right or in a'clockwise direction as seen inFig. 2, are adapted to bind against the projecting end` por? tions 17aof the bars to lock them stronglyy and securely against the surface ofthe door portion 10,' to thus hold the doors against folding'k movement;while, upon turning of the shaft to the left the cam faces first releasethe bar ends 17?, and vthen move out from behind thesame altogether topermit said ends to swing Aoutward as Athe doors fold, this occurringwhen the shaft has been 'y turned approximately a one-half rotation ing.

50 moilenient as already described.

being likewise secured to the squared shaft by a clamp screw Q8. Theposition ot' the handle 27 with respect to the cams 22a is such that itextends alongside the doors to 5 the left thereof as seen in Fig. 2 whenthe lla. fixed stop shoulder 30 formed yon the bracket 1.9. ln caseswhere by reason oi )smaller dimension oi? the doors or for other reasonsit is not necessary or desirable to have cam. locking devices asdescribed at both 'top and bottom `of the door, it is practicable toemploy a simplified and more compact form of the device with the binderand operating handle at an intermediate point in the height of the door.Such a form is shown in Figs. 4 to 6 wherein two door p0rtions 100,110are hinged at 120. The door portion 11() has at an intermediate point inthe height thereofV ,a stout bar 17 O'iixed thereto witha projectingportion 170a which isadapted to be pressed against the portion 100similar-ljv as the bars 17 already ydescribed. ln this case a singlebracket 19() is secured to the door portion 1.00 and this is equippedwith bearing collars 1901 vertica .ly spaced apart. rEhe lower one ofthese bearii'in collars has fitted therein a reduced hub of a cam head220, while the upper collar has fitted` therein a hub extending 'from ahead 2G() which bears a handle 270.

j0 The cam head 220 is equipped with a cam face 220 adapted to cooperatewith the bar projection 1r@a tor binding act-ion similar as in thedescribed form. rl`he heads 220, 260 have squared socket passagestherethrough in which is fitted a squared shaft or bar i280, to whichsaid heads are secured.y The handle head i260 bears a shoulder 290adapted to engage a stop shoulder 300 on the bracket plate 190 to limitthe handle that the invention may be embodied in other spcilic formswithout depa-rtingfrom the spirit or essential attributes thereof, and ltherefore desire the present embodiment to be considered in all respectsas illustrative and not restrictive, reierence being had to the appendedclaims rather than to the foregoing description to indicate the scope ofthe invention.

vmeans for holdingsaid portions against il I am aware Having describedmy invention, what I claim as new and desire to secure by Letters Patentis:

1. The combination with two door portions hinged together for folding,of a binder Q. The combination with two door por tions hinged togetherfor folding, of a binder for holding said portions against folding.composed ci a b a-r secured to one oi said portions and projecting tooverlap the other portion, rock sha-'it journalled to the other doorportion bearinga cam adapted in one position to engage said barprojection with a binding action and in another position to release thebar, and a handle for operating said rock shaft.

3. rlfhe combination with two door portions hinged together 'l'orfolding, of bind-` ing means iior holding said portions against folding,composed of loa-rs secured to one oi the door portions acent the top andbottom thereof and projecting to overlap thc other door portion, and a.rock shaft journalled to turn in brackets secured to the other doorportion lwith cam heads at its extremities bearing cam faces adaptedl eoengage bar projections and a handle Fixed to saidy rock shaft at anintermediate point and journalled in abracket secured to the second doorportion.

4i. The combination with two door por tions hinged together 'forfolding, oi' bin d' ing at will, composed of a bar secured to one oi'said `rportions and projectingto overlap the other portion, a bracketsecured to said other door portions, a cam head having a hub fitted inbearingco'llar oi said bracket and ,bearing a. cam face adapted toengage saidbar projection to bind it against lthe door portion, a rockshaitt in said cam head, and a handle fixed to said rock shaft Vandhaving a head equipped with a hub ournalled yin a bearing collar iixedwith respect to said bracket.

ln testimony whereof, I have signed my name to this specication. l
